DISK DRILL.

Specification of Letters Patent.

Patented Feb. 2, 1909.

To all whom it may concern:

Be it known that I, CHARLns H. PEL'roN,

citizen of theUnited States, residing at Springfield, in the county of Clark and State of Ohio, have) invented certain new and useful Improvements in Disk Drills, of which the foilowingis a specification, reference being had therein to the accompanying orawmgs.

The present invention'relatesto disk drills and has for its object the production of a drill of this character in which the disks can be adjusted transversely of the machine to vary the distance between the several disks and thereby vary the distance between the rows of grain planted; the provision of mechanism whereby the adjusting of the disks may be accomplished simultaneously and from a convenient point in the rear of the drill; and the provision of means whereby the disks will all be maintained in proper relation with the ularities therein.

With these objects in view my invention consists in certain novel 'featuresof construction to be hereinafter described, and then more fully pointed out in the claims.

In the accompanying drawings, Figure 1 is a top plan view of a drill embodying my invention; Fig. 2 1s a side elevation of the same; Figs. 3, 1 and 5 are detail sectional I views showing the adjusting mechanismin its several positions; and Fig. 6 is a detail view of one of the disks and its supporting mechanism.

In these drawings, I have illustrated my invention as applied to a five disk drill of ordinary construction, but, obviously, the invention can be adapted for use in connection with any drill of this general type. The drill, as here shown, consists of the main frame 1, having the traction wheel2 journaled near the forward end thereof and provided at its rear end with a seed'hopper 3 mounted above the frame and provided with flexible seed tubes 4 which connect the hopper with the boots 5. The guide bar or shaft 6 is mounted transversely of the frame 1 intermediate its ends and has mounted thereon a plurality of supports or sleeves, preferably three in number, the central sleeve 7 being journaled on the shaft 6 and held against longitudinal movement thereon, while the two outer sleeves Bare journaled on the shaft6 and are free to move longitu ground regardless of irregdinally thereof. The sleeves are similar in constructlon and each has a rearwardly projecting arm or bracket9, to which is secured one end of the drag bar 10, to the opposite end of which is secured the bracket 11 carry-- ing the boot 5 and the disk 12. These disks are free to move vertically to a limited extent. Each supporting bracket 11 is provided with an upwardly extending rod 13 pivotally connected thereto, and, in the present instance, this rod is shown as pivotally connected to the boot 5 carried by the bracket 11. The rods 13 extend upwardly through guideways 1 1 in the frame 1 and are provided at their upper ends with a stop, such as the key 15, to prevent their withdrawal from the guideway. A spring 16 is coiled about the rod 13 and-is confined vbetween the frame and a suitable stop near the lower end of the rod, such as the washer and split key 17. The drag bars 18 for the two outer disks are of much greater length han the drag bars 10 and are pivoted to the frame near the forward end thereof and adapted to swing in a horizontal plane. These drag bars extend toward the rear of the drill to a point substantially in alinement with the rear ends of the drag bars 10 and are there provided with the bracket 11, boot 5 and disk 12, as are the drag bars 10. The rear'ends of the drag bars 18 are connected with the main frame by a bar 19, which is connected to the boot at 20 and pivotally connected to the hopper at 21. The pivotal connection of the bar 19 to the hopper is such as to allow the boot and disk to move laterally, but to hold the same against movement in a vertical plane.

The central sleeve 7 which is mounted on the shaft 6, is provided with an upwardly extending bearing lug 22, extending transversely of the shaft 6 and adapted to receive a rod or shaft 23 which is mounted to slide longitudinallythereof and to rotate therein, and is provided with a stop, such as a split key 24, to prevent its withdrawal from the bearing lug. The bar 23 extends to the rear of the machine beyond the feed hopper where it extends through an apertured guide 25 and has its rear end bent at right angles to the main portion thereof to form a handle 26. The guide 25 is provided in its rear face with a seriesof recesses 27 preferably placed at intervals of ninety (90) degrees and adapted to receive the handle 26 and hold the same against lateral movement. A spring 28 is coiled about the rod 23 and confined between the front wall of the guide 25 and a suitable stop on the rod 28, such as the washer and split key 29. This spring serves to hold the rod normally in its toremost position with the handle 26 in one of the recesses 27, thereby preventing the rotation of the rod 23 about its longitudinal axis.

A collar is mounted on the rod 23 near the shaft 6 and is so connected thereto as to rotate with the rod, but to allow the same a free longitudinal movement relatively thereto. The collar 30 is provided with oppositely extending apertured arms 81, adapted to receive the pivot lugs 32 of the connecting rods 83, the pivot lugs, in the present instance, being formed by turning the inner ends of the rods at right angles thereto and inserting these end portions through the aperturesof the arms 81. The opposite ends of the rods are pivotally connected to the brackets 9 of the outer sleeves 8, preferably by turning the outer ends or the rods to form hooks 34, which extend through apertures formed in the brackets 9. The outer sleeves 8 are provided on their lower sides with apertured lugs or eyes adapted to receive the adjacent ends of the rods 36, the opposite ends of which extend through similar apertured lugs or eyes 37 carried by the drag bars 18. These rods are provided on their outer ends with nuts 88 to prevent their withdrawal from their respective bearing lugs and may be held in their relative positions to the several drag bars in any suitable manner, but I prefer to accomplish this by means of a spring 39 coiled about the rod 6 and confined between the apertured lugs and 37 and serving to hold the drag bars 18 normally in their extended position, but allowing a limited lateral movement of the same.

The operation of the device will be obvious from the foregoing description. With the adjusting mechanism in its normal position, that is, with the crank arms 31 in the position shown in Figs. 1 and 5, the drag bars are in their most widely separated position and the rows planted are separated by the widest possible space. By grasping the iandle 26 or" the rod 23 and moving the same rearwardly against the compression of the spring 28 until it is released from the recess 27 and then turning the same through an arc of ninety (90) degrees and allowing it to engage the next recess 27 the arms 3i will be turned to a position at right angles to the position which they formerly occupied, as shown in Fig. at, thereby moving the sleeves 8 toward the central sleeve 7 and, consequently, the disks carried by such sleeves toward the disk carried by the central sleeve 7 and lessening the distance between the same an equal amount. The drag more in unison with the sleeves 8 and the drag bars will be moved at the point of their connection with the sleeves a distance equal to the distance which the sleeves move, and. this point is considerably in the rear of the disks carried by the drag bars, the disks will move through a considerably greater distance than do the central portions of the drag bars. Thus by making the connections between the drag bars 18 and the sleeves H at the proper distance from the rear ends of the drag bars the dilvs carried by these drag bars can be caused to move twice the distance which the disks connected to the sleeves 8 are caused to move, thus maintaining thr same distance between the disl s connected to the drag bars l8 and the dis is connected to the sleeves 8 as is maintained between these latter disks and the disks carried by the central sleeve T. liy moving the handle to rotate the shaft 23 through a further are of ninety (90) degrees, the crank arms 31 are moved to a position the reverse of that which they ori inally occupied, as shown in i 3. the rods 33 being bent outwardly 1e to allow them to pa around the shaft and permit the arms 31 to assume a hori zontal position, thus moving the drag bars to their innermost position and adjusting the distance between the disks and the rows planted thereby to the narrowest possible spac Further, it will be ap 'iarcnt that the adjustment of all the disks is accomplished simuihnicously by the operation of but a single lover or handle and that this adjustment is positive and necessarily nnvarying. The disks carried by the drag bars 18 being held against YQlllill movement while the intermediate disks are permitted to move vertically, provides what is practically a three point support ior the drill, the traction wheel 2 serving as the forward support and the disks carried by the drag bars l'tl serving for tac oth 2r two supports. This construction is such that the (ir'ks wlll all be in opera en aa'cmcnt with the ground at all dlcss (ii any irregularities therein sult will be zwcomplishcd without he stability and the steering quali- 1e drill. The traction wheel serves ties oi as a point of pivotal support for the l rame and the two outer disks are held in positive engagement with the ground. while the inner d isks are capable of vertical movement, as above described, and. should any irregularities occur in the ground intermediate the outer disks, these intermediate disks will rise or fall to accommodate themselves to this irreularity, and. in the ease of a depression in til" ground, will sink to the lower surface thereof and properly plant the grain, while oil erases in the case of an elevation they will ride over the same without tilting the frame of the machine and thereby raisingthe outer.

ment therewith by their springs, and, as

stated, this result isaccomplished without affecting the stability of the machine, as is the case where all the disks are spring mounted, as such a construction causes the machine to wabble badly and renders the steering thereof a very difficult matter.

I wish it to be understood that I donot. desire to be limited to the exact details of' construction shown and described, forobvious modifications will occur to a person skilled in the art.
